[Open Source] Design of a Bluetooth-controlled car system based on STM32

"Bluetooth controlled car based on STM32" is a motor driver module, power management module, STM32 main control module, Bluetooth serial communication module, and Android control end module based on STM32 development board. The motor driver module uses two L298N chips to drive 4 motors. The enable end is connected to 4 PWM wave signals from the main control board, and the 8 input ends are connected to the 8 output ports of the main control board; the power management module uses the LM2940-5.0 chip to convert 12V to 5V. 12V is used to power the motor module, and 5V is used to power the Bluetooth module, sensors, etc.; the main control module uses the MDK editor program, and then downloads it to the main control board to realize the interaction between hardware and software; the Bluetooth serial communication module uses the FBT06_LPDB pin-plug Bluetooth module to communicate with the main control board via serial port and communicate with the Android phone at the same time; the Android control end module is a set of functions such as turning on Bluetooth, searching Bluetooth, and controlling the car. Users can control the movement of the car through the Android control end to realize some functions and services required by users.
